Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Non-coherent and Differentially Coherent code acquisition in MIMO assisted DS-CDMA multi-path downlink scenarios

, 2008
In this contribution we investigate both Differentially Coherent (DC) and Non-Coherent (NC) code acquisition schemes in the Multiple Input Multiple Output (MIMO)-aided Direct Sequence-Code Division Multiple Access (DS-CDMA) downlink, when communicating ...

The recent progress in terahertz channel characterization and system design

Discrete and Continuous Models and Applied Computational Science
As the standardization of 5G New Radio (NR) systems operating in micro- and millimeter-wave frequency bands is over, scientific and industrial communities have begun to address the question of what 6G communications systems might or should be.

Integrating Time‐Adjusted Imaging Instability Into Functional Outcome Prediction After Intracerebral Hemorrhage: Development and Validation of the HAGIV Score

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early risk stratification may support clinical decision‐making in spontaneous intracerebral hemorrhage (ICH). We aimed to develop and internally validate HAGIV, a score integrating frequency of imaging markers (FIM), a time‐adjusted non‐contrast computed tomography (CT) metric of hematoma expansion, with established predictors for 90‐

Mapping the Social Network Structure and Composition of Black Individuals With Rheumatic and Musculoskeletal Conditions

Arthritis Care &Research, EarlyView.
Objective Our objective was to describe the social networks of Black individuals with rheumatic and musculoskeletal conditions and understand the clustering of health‐related behaviors to inform future community‐based, peer‐led interventions. Methods We used an adapted Personal Network Survey for Clinical Research (PERSNET) to map the personal social ...

COMMUNICATION THEORY AS A COHERENT FIELD IN THE CONTEXT OF MANAGERIAL INFLUENCE AT THE TURN OF THE XX–XXI CENTURIES

Векторы благополучия: экономика и социум, 2021
The relevance of the study is determined by the need to identify the context of managerial influence in foreign studies of the communication theory in the late XX – early XXI centuries with the prospect of constructing social processes in modern society.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Lifespan associated global patterns of coherent neural communication

NeuroImage, 2020
Healthy ageing is accompanied by changes to spontaneous electromagnetic oscillations. At the macroscopic scale, previous studies have quantified the basic features, e.g., power and frequencies in rhythms of interest from the perspective of attention ...
